Guide To AEG GearsGears are a set of internal components that are inside your AEG gearbox. Gears transfer energy from the motor to the piston that in turn pulls the spring back and releases it, thus giving your AEG power. There are four main gears found inside an AEG gearbox. The pinion gear, the spur gear, the bevel gear, and the sector gear.
Pinion Gear: This is the gear connected to the motor axel. It is the first gear coming from the motor, the AEG’s electrical power source. This gear spins the bevel Gear.
Bevel Gear: This gear gets its energy from the Pinion Gear and then spins the next gear.
Spur Gear: Gets its energy from the Bevel gear and transfers energy to the next gear.
Sector Gear: This is the final gear in the assembly its job is to pull the piston back.
*The point of all of these gears is to transfer energy from Point A- The motor, to Point B- the Piston.
Gears come in different shapes and sizes. All designed to fit in their designated gearboxes.
Gear Ratios: A gear ratio in an AEG is how many revolutions the pinion gear turns per one complete Sector revolution. Ex. 18.72:1 Final Ratio means 18.72 pinion revolutions per sector gear
These gear ratios are typically divided into three different gear categories.
- High Speed: High speed gears have a lower ratio and will increase your rate of fire as it takes a lower amount of pinion revolutions to complete a complete a cycle.
- Standard: In between high speed and high torque. Regular Gear set; most AEGs come equipped with these, they are typically 18.X:1.
- High Torque: High Torque gears are intended to be used with high power springs only. They boast lower RPMs but the torque figure is high. Torque gears will result in a delay in AEG cycle response time.
- Helical Gears: These are the teeth you will find in your car’s transmission. The teeth on these gears are cut at an angle so that the gears engage gradually by having the contacts starting at one end of the tooth and nicely spread across as the gear rotates. These gears will mesh better with each other than regular gears and you’ll get more surface area on your gears. The benefit is that the gears run very smoothly and will run with less operating noise and can increase gear reliability (if installed and shimmed properly).
